Figure 18: Input Terminal Ripple Current, ic, at full rated output cur-
rent and nominal input voltage with 10H source impedance and 47F
electrolytic capacitor (500 mA/div). See Figure 17.
Figure 19: Input reflected ripple current, is, through a 10 H source
inductor at nominal input voltage and rated load current (10 mA/div).
See Figure 17.
Figure 20: Output voltage ripple at nominal input voltage and rated
load current (20 mV/div). Load capacitance: 1F ceramic capacitor
and 10F tantalum capacitor. Bandwidth: 20 MHz. See Figure 17.
